Emerald Cave

Emerald Cave is a marine cave in Ko Libong with a natural tunnel leading to an interior pool. Sunlight filtering through openings in the limestone creates distinctive green reflections on the water surface.

Local fishermen have navigated these Andaman waters for generations, knowing this cave as a natural shelter along their traditional routes. It served as a landmark within the fishing community's established seaways.

The location holds spiritual significance for local communities, reflected in traditional stories about supernatural beings said to dwell within the stone depths. Visitors can sense this connection to local tradition while paddling through the narrow passage.

The cave is best accessed by kayak or boat departing from the main beach, making for a short water journey. Morning visits work best when natural light is strongest and crowds remain smaller.

The interior saltwater pool creates a natural swimming space accessible only through the tight tunnel opening, requiring a genuine paddling effort even in calm conditions. This seclusion makes the visit feel more adventurous than typical tourist cave experiences.
